If DTC U2024:41 is retrieved again, A guided routine is not applicable for this vehicle and market. Replace the component that was faulted through diagnosis. |
| U2100:00 | Initial Configuration Not Complete: No Sub Type Information | CHECK the vehicle service history for recent service actions related to the PAM. This DTC sets due to incomplete or incorrect PMI procedures. If there have been recent service actions with this module, REPEAT the PMI procedure using as-built data. REFER to: Module Configuration - System Operation and Component Description . If there have been no recent service actions, A guided routine is not applicable for this vehicle and market. Replace the component that was faulted through diagnosis. |
| U2101:00 | Control Module Configuration Incompatible: No Sub Type Information | CHECK the vehicle service history for recent service actions related to the PAM. This DTC sets due to incomplete or incorrect PMI procedures. If there have been recent service actions with this module, REPEAT the PMI procedure using as-built data. REFER to: Module Configuration - System Operation and Component Description . If there have been no recent service actions, A guided routine is not applicable for this vehicle and market.
